Description

Technical Field

[0001] The present invention relates to the technical field of hair clipper blade production, and particularly to an automatic assembling machine for hair clipper blades. Background Art

[0002] Hair clipper blades generally include an iron knife holder and a blade assembled with each other. When manufacturing hair clipper blades, after bending a sheet-shaped knife holder into a U shape, a blade is placed on the knife holder. After the blade is placed on the knife holder, the blade and the knife holder are riveted together through a riveting device to form a hair clipper blade. Currently, the production of hair clipper blades is all carried out in a production line manner. After the knife holder is bent manually, it is moved to the next workstation through the production line. Workers pick up the bent knife holder at the next workstation and place the blade on the knife holder. Finally, the blade and the knife holder are riveted together through a riveting device. Manufacturing hair clipper blades in the way of manual production line occupies a large area, has low efficiency, and workers are easily cut by the blades when manually picking up and placing the blades for riveting.

The lowermost knife box in the knife box chute drops to one side of the knife box push plate again. The riveted hair clipper blades are grabbed by the manipulator and then moved into the knife box at the position of the knife box fixing groove. When a certain amount of hair clipper blades are placed in the knife box, the motor is started. The motor drives the lead screw to rotate. Since the lead screw passes through the knife box slider and is threadedly connected to the knife box slider, and the knife box slider is slidably connected to the frame, when the lead screw rotates, the knife box slider moves to the position of the material receiving guide rail. The knife box pushing-away cylinder is started. The piston rod of the knife box pushing-away cylinder extends.

After the in-box grasping cylinder moves to directly above the hair clipper blade and is activated, the grasping block sucks the hair clipper blade and places it in the knife box. By setting the turning device, the hair clipper blade can be turned 180 degrees. After the hair clipper blade is riveted and formed, the edge of the blade faces upward. By turning the hair clipper blade 180 degrees through the turning device, the edge of the hair clipper blade faces downward, and then the hair clipper is placed in the knife box, avoiding the consumer cutting their fingers when taking the blade with the edge facing upward.

After the grabbing block 907 made of permanent magnet sucks the hair clipper blade of the flipping device 11, the inserting pushing cylinder 901 is activated again, the piston rod of the inserting pushing cylinder 901 extends, the inserting grabbing cylinder 906 reaches directly above the knife box 14, the piston rod of the inserting grabbing cylinder 906 extends, and the hair clipper blade is inserted into the knife box 14. After the hair clipper blade is inserted into the knife box 14, the holding force between the hair clipper blade and the knife box 14 is greater than the gravitational force between the grabbing block 907 and the hair clipper. The inserting grabbing cylinder 906 is activated, the piston rod of the inserting grabbing cylinder 906 shortens, and the grabbing block 907 is separated from the hair clipper blade. Through the blade inserting device 9, the formed hair clipper blade can be placed in the knife box 14 without manual blade placement, further avoiding cuts.

[0034] Among them, a flipping device 11 is also fixed on the frame 1. The flipping device 11 includes a rotary cylinder 111 fixed on the frame 1. A clamping finger cylinder 112 is fixed to the output end of the rotary cylinder 111. Clamping plates 113 are fixed to both output ends of the clamping finger cylinder 112. After the riveted hair clipper blade is placed between the clamping plates 113 by the in-box finger cylinder 904, the clamping finger cylinder 112 is activated. The two clamping plates 113 close towards each other. After the hair clipper blade is grabbed by the clamping plates 113, the in-box lifting cylinder 903 is activated, and the in-box finger cylinder 904 rises. After the in-box finger cylinder 904 separates from the hair clipper blade, the rotary cylinder 111 is activated, and the clamping finger cylinder 112 rotates 180 degrees. After the in-box grasping cylinder 906 moves to directly above the hair clipper blade and is activated, the grasping block 907 sucks the hair clipper blade and places it in the knife box 14. By setting the flipping device 11, the hair clipper blade can be flipped 180 degrees. After the hair clipper blade is riveted and formed, the cutting edge of the blade 13 faces upward. By rotating the hair clipper blade 180 degrees through the flipping device 11, after the cutting edge of the hair clipper blade faces downward, the hair clipper is placed in the knife box 14, preventing the consumer from cutting their finger when taking the blade 13 with the cutting edge facing upward.
